Abstract: A computer program product for scenario-based source code inspection is provided. The computer program product comprises a computer-usable data carrier storing instructions that, when executed by a computer, cause the computer to display a plurality of functions, the plurality of functions comprising: a first function for creating one or more scenario paths in the source code by providing the ability to create hyperlinks from subroutine/macro calls to the subroutine or macro source in the code and commentary addition; and a second function for inspecting code in execution order and inspecting uninspected lines of code by providing the ability to annotate the code with any errors and observations found and mark lines inspected.

Abstract: A method and system for injecting a deterministic fault into storage shelves in a storage subsystem. The method comprises injecting a known fault condition on demand into a hardware component in a storage shelf to cause a failure of the storage shelf. The hardware component incorporates a circuit that is configurable to select between a normal operating condition and a faulty condition of the hardware component. The method further comprises verifying that a reported failure is consistent with the known fault condition.

Abstract: A drive shelf includes an embedded switching hub (ESH) that monitors Fibre Channel Arbitrated Loop (FC-AL) traffic, including loop initialization requests (LIRs), coming from drives attached to the ESH. When a number of LIRs issued by a single drive within a certain amount of time exceeds a threshold, the drive is bypassed. One threshold (a “burst” threshold) measures the number of LIRs issued within a short period of time. If the number exceeds a threshold that would prevent other data from circulating through the loop, the drive is bypassed. A second threshold (a long-term threshold) measures the number of LIRs issued within a longer period of time. If the drive issues a number of LIRs at a slower rate than the burst threshold, but still above the long-term threshold, the drive is bypassed.

Abstract: A storage tank for storing and selectively dispensing pressurized combustible fluid comprises a main tank having a delivery outlet, and a first valve mounted on the main tank in fluid communication with the delivery outlet for controlling the flow of the pressurized combustible fluid from within the main tank to the ambient surroundings. A reserve tank is mounted in supported relation on the main tank and has a reserve outlet disposed within the main tank to permit direct fluid delivery from the reserve tank into the main tank.
